the answer is 4
just think of -4 as 4 in this question it is looking for the one closer and now that both of them are counting numbers 4 is less
31 is the answer because you would do 5 x 3 an that's 15 and if it's squared u technically add 15 a second time
In standard form the answer will be if you go by (Ax+by=c )then I must say it's 3x-7y=9
